    Does your laser system always produce the exact same energy output? One may be tempted to assume that lasers always produce energy as per their specifications and that it never changes over time. The reality is often very different.

    Many elements such as the optical components and surrounding environment have an impact on the energy your beam delivers. The intrinsic noise of the pulsed laser is also an important factor since it has a large impact on pulse-to-pulse energy stability.

    • If you manufacture medical equipment, you need to ensure patient’s safety and guarantee good operation for your customers.
    • If you integrate LIDAR system you can’t afford to have variation in laser energy from pulse-to-pulse, otherwise, the reflection would be meaningless.
    • If you do nuclear fusion research, you need to monitor all the laser lines that operate the system at different checkpoints in order to produce the desirable results.

    In this webinar, you will learn how to measure laser energy accurately. You will also discover the tools that can help you maintain standardized quality and ensure end-users’ safety, therefore ensuring the success of your operations.

  • Gentec-EO Blu Series honoured at Laser Focus World's Innovator Awards 2020

    Gentec-EO Blu Series honoured at Laser Focus World's Innovator Awards 2020

    HP280A-30KW-HD-IMP-BLU-D0: High power detector for laser power measurement up to 30000 W. With BLU (Bluetooth) embedded wireless monitor. Includes USB Bluetooth receptor.

    This year again Laser Focus World held its Innovators Awards program, which celebrates innovative technologies, products and systems found in the photonics market. We are proud to share with you that the Gentec-EO HP-BLU series was selected as Bronze-level honoree.

    The HP-BLU series wireless detectors for high-power lasers for laser power measurement up to 15 kW integrate a wireless data-transfer module that allows for remote monitoring at up to 30 m from the detector and is battery-operated to reduce cabling.

    THE HIGHEST POWER HANDLING: Custom models handle up to 100 000 W of continuous power. Higher powers are available upon request.

    STABLE READING: Less sensitive to variations in water cooling temperature than any other high power watercooled meter on the market.

    INFINITE CUSTOMIZATION CAPABILITIES

    1. Choose your size

    2. Choose your maximum power

    3. We will customize one just for you!

    COMPACT AND LIGHT WEIGHT: Lighter and more compact than any other high power detector on the market, thanks to our unique design.

    AVAILABLE WITH YAG AND CO2 CALIBRATION: All HP models can be calibrated at YAG and CO2 wavelengths with a calibration uncertainty of +/- 5%.

    DIRECT USB CONNECTION TO A PC: Each head comes with both a DB-15 connector (for use with a Gentec-EO monitor) and a USB2.0 output for direct connection to a PC. Other connectors available upon request.
